Angiotensin II Pathway and Postoperative Hypoxemia

Acute type A aortic dissection is often accompanied by postoperative hypoxemia, the cause of which is not fully understood. Angiotensin II is an important component of the renin-angiotensin system (RAS), which has been suggested to be involved in the development of aortic dissection and pulmonary inflammation.The purpose of this study was to investigate the role and mechanism of angiotensin II pathway in postoperative hypoxemia after acute type A aortic dissection, and to provide reference for clinical application
